I'm playing at 1440p 144hz, and I'm planning to upgrade to one of these cards. I have a PCIE 4.0 motherboard and a 750W power supply, so I'm confident that I can support both cards, but I'm not sure which would be better for me. I'm planning to keep whichever card I get for six years, and while both of them are probably overkill for the resolution that I'm playing at, I'm not sure how well they'll hold up six years later. Should I buy the 3080 to be safe? Or is the 3070 powerful enough to last?
